Modular Construction

Holtro Modular projects are constructed in a controlled factory environment and are delivered to site as completed prefabricated modules. From design, each building will meet client requirements, engineering and energy efficiency to achieve the required standard and compliance of the Building code of Australia for council approval. All materials used are of a premium standard. Through each stage of construction our qualified teams must meet strict quality control standards. Prior to transport all buildings are inspected and certified. Our construction methods provide the opportunity to take control of the quality and speed of completion which will ensure our on-site works and disruptions are minimised. Each project is constructed to the highest degree of finish for handover to our clients.
